Livni, who was sitting next to Gabbay during the announcement, had not been informed of the Labor leader's plans ahead of time.

Gabbay appeared to criticize Livni’s faction during his announcement, saying that the partnership between the two parties had failed to “lead to real growth” and suggesting Livni’s party had failed to “stand by agreements”.

Later, Livni tweeted a message directed at supporters, vowing to carry on despite the termination of Zionist Union joint list.

“Thank you to the callers, the SMS senders and the supporters. It is good that the doubts have been dispelled and we can focus on the important national challenge we face, all those who believe in the truth of our path - a revolution [will be coming] in the upcoming elections,” she wrote.
